OCTEON II CN68XX Family of Multi-Core MIPS64 Processors

16 to 32 cnMIPS64 v2 cores processors for high-performance, high-throughput, service-rich applications in secure data center, mobile internet, and enterprise applications

OCTEON II CN68XX Multi-Core MIPS64 Processors

The Marvell® OCTEON® II CN68XX family of multi-core MIPS64 processors targets high-performance, high-throughput, service-rich applications in secure data center, mobile internet, and borderless enterprise applications. The family includes six software and pin-compatible processors, with 16 to 32 cnMIPS64 v2 cores, over 85 application acceleration engines, and innovative real-time Power Optimizer features, providing the highest compute and services performance of any standard ISA processor. 

Supported by industry-standard software toolchains and operating systems, the CN68XX offers 2X to 5X performance, power, and real-estate advantage over alternatives, and is fully software and pin-compatible with the OCTEON II CN67XX 8 to 16 processors, enabling scalability from 8 to 32 cores with the same hardware and software design.

OCTEON II family is fully software-compatible with the widely-adopted OCTEON Plus family, enabling straightforward software reuse. Powerful control plane processing solutions are enabled with high-frequency cores up to 1.4GHz, large and highly-associative L1 and L2 caches, and up to 400Gbps of DDR3 DRAM bandwidth.
